+If you would like to disable the caching for Kafka consumers, you can set
`spark.streaming.kafka.consumer.cache.enabled` to `false`. Disabling the cache
may be needed to workaround the problem described in SPARK-19185. This property
may be removed in later versions of Spark, once SPARK-19185 is resolved.

the burden of keeping it around is low, and I don't expect we'd ever get around
to removing it anyway.
